Reserve Rights is an Ethereum-based stable token that is built on the Reserve Protocol. Reserve token will be initially backed by several other collateral tokens that are each tokenized versions of the US Dollar. The project has plans to transition to a collateral model that will not be pegged to the US Dollar.

The Maker token (MKR) is the MakerDAO native token. It acts as a utility token, governance token and a recapitalization tool for the MakerDAO platform, which manages the DAI stablecoin. MKR is used as part of the stabilizing mechanism that is in place to combat the price volatility of the DAI stablecoin.
DAI is pegged to the US dollar and has collateral in place to ensure stability. The MKR token is used is to pay for the "collateralized debt positions" (CDPs) that have been used to generate DAI. After this MKR is used, it is removed from the supply. MKR holders also contribute to the governance of the MakerDAO and vote on crucial issues related to the direction of the DAI stablecoin.

The Multi-Collateral DAI stablecoin uses multiple types of collateral to back its value and an interest rate mechanism to stabilize its price. It is designed to be a digital currency with a stable value. MakerDAO is the decentralized autonomous organization that manages DAI and works to combat its price volatility. Multi-Collateral DAI was launched in November, 2019 and is meant to be a successor to the Single-Collateral DAI, that will eventually be phased out. The new stablecoin will enable new features to the Maker Protocol, such as the the Dai Savings Rate (DSR), as well as additional types of asset collateral.
